Al Maki For one thing, it's actually realistic. Jorge Luis Borges was blind most of his life and he said the one color he never saw again after he became blind was black. He saw a numinous field that was usually blue. Another thing, if you take the book as a parable, which given the fact that the author was a life long communist seems reasonable, then the blindness could be a result of cultural brainwashing, i.e. the blocking of real information by overloading the eyes, as Bruce Springsteen put it "blinded by the light."
Jennifer I think the 'white blindness' is symbolic of how although people may have the light to see, they don't see; this ties in with the extended metaphor of the novel.
Carlos Cabrera Some answers missed the point it is a metaphor for human iteration, and finally, for lost democracy. We can see, we just choose not to.
Johanna Gutierrez desde que inicie a leer el libro me atrapo!, es muy interesante como nosotros nos hacemos ciegos de tantas cosas que pasan en el mundo..., de que vale ver si no hacemos nada positivo???
Niloofar In my opinion that's something symbolic in the book. in fact seeing the things white means that you are optimist. So in the book the writer is showing a society in which the people go blind so they cant see anything and at the same time everything is white so they cant see the facts and they are optimist just because of that blindness
